We’re having a company come tonight to give us an estimate to waterproof our whole basment. We’re looking at exterior french drains and possibly interior with a sump pump. Aside from cost (which we plan to ask lol) Are there any more good questions you can think of? We get a small to moderate amount coming from the bottom of three of the walls.

Questions to ask so far:

-Do you have a guarantee or warranty?

– How long does it take?

– Do you perform the work yourself or do you hire other workers?

– How do you work around machinery such as our furnace, and oil tank?

I am crazy and I want to make sure we don’t miss any opportunities! Anyone had this done and can shed some light on things they wish they would’ve known, or good questions we should ask?
